Abstract
A load driver circuit includes a detection circuit periodically detecting an inrush current that flows to the detection capacitor from the first terminal through the first switch element and outputting a detection signal responsive to a result of the detection at the first node; a peak hold circuit holding a peak voltage of the detection signal and outputting the held peak voltage as a detection voltage; a comparison circuit comparing the detection voltage with a threshold voltage and outputting a comparison result signal responsive to a result of the comparison; a control circuit controlling the first switch element to switch on and off, controlling a current detection operation of the detection circuit, and outputting a load control signal that controls the operation of the load; and a logic circuit controlling the load switch element based on the comparison result signal and the load control signal.
